🌱 How to Care for Hybrid Tulip to Prevent Powdery Mildew?

💧 How to Water

Water deeply right after planting bulbs in autumn. During the growing season, water every 5–8 days depending on rainfall and temperature. Avoid waterlogging — soggy soil quickly causes bulb rot. Reduce watering once blooms fade and foliage yellows.

☀️ Lighting

Tulips require at least 6 hours of direct sunlight daily for the best flowering. A bright, south- or west-facing spot is ideal. Insufficient light causes tall, floppy stems and poor blooms.

🪴 Ideal Soil

Plant in well-draining, loamy or sandy soil enriched with compost. Avoid heavy clay that retains moisture. Ideal pH is 6.0–7.0. In containers, use a gritty potting mix with extra perlite for drainage.
